Confocal immunofluorescent analysis of Presenilin 1 (PSEN1) Antibody (C-term) with MDA-MB435 cell followed by Alexa Fluor 488-conjugated goat anti-rabbit lgG (green). DAPI was used to stain the cell nuclear (blue).

Presenilin 1 (PSEN1) Antibody (C-term) flow cytometric analysis of Hela cells (right histogram) compared to a negative control cell (left histogram). FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

All lanes: Anti-PSEN1 Antibody (C-term) at 1:1000 dilution. Lane 1: Hela whole cell lysate. Lane 2: HL-60 whole cell lysate. Lysates/proteins at 20 µg per lane. Secondary Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated at 1/10000 dilution. Predicted band size: 53 kDa. Blocking/Dilution buffer: 5% NFDM/TBST.

Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.

A dominant 59.6 kDa band and faint 87.6 kDa band for both the Hela wild type and knock out lysates were observed (3 ug/ml anti-PSEN1) vs the predicted size of 52.7 kDa. The molecular weight discrepancy could be due a post-translationally modified form of the target protein, a splice-variant form of the target protein, or an unrelated protein which shares the antibody-reactive epitope. The presence of bands in the knock out lysates suggest incomplete knockout of the target gene.
